You could always use placeholders. I wish I was of more help, but realistic art is pretty damn hard to make look good. You won't get a lot of it asking around a small forum like this one.

You could certainly search around on DeviantArt for freelance artists willing to do some artwork for you. Some will want pay, but I'm sure there are some out there that will be willing to do it for no compensation (not a LOT of people, but there are some).

I'm posting a quick test to see if this is the kind of thing you're going for. it's pretty vague, so let me know if you want more detail... I can definitely do more detail. Lots more ideas in my head than this.

Bequethi is the God of the Elves. He represents all Elves, and is usually a part of every Elven pantheon of some form or another, even the Dark Elves. Many Elven societies share the fable the Bequethi was once a normal Elven minister, who rose to enlightenment and glory by driving off the demonic hordes of the Northern Hinterlands and stealing their wisdom. The story, while mostly exaggerated, serves as an inspirational tale for many Elven youths.

Bequethi is usually at the head of any of the various mainstream Elven pantheons (analogous to Zeus in Greek mythology). He is often portrayed as a tall, sharply featured man with longer-than-average ears and flowing purple robes, carrying an intricate golden glaive. His holy symbol is that of an ancient tribal Elven doll design, the same insignia supposedly used on Bequethi's war banners.
